Drake Merlin falls in love with Ana, a fellow student. Their life together is bliss, with Drake composing
high quality, albeit little known, musical works and Ana a successful concert singer. When Ana falls ill, there
is little that medical science can do for her. Drake puts together a plan where she is to be frozen and put in
suspended animation, until there is a cure for her condition. Once she is frozen, he starts the other half of
his plan -- for himself to be frozen until they both can be together.

When he is awakened five centuries later, the reason is not that a cure has been found for Ana. Instead, a music
historian has reawakened Drake so that Drake can provide guidance about "ancient" music. The people of 2512
find his single-mindedness of curing and reviving Ana to border on mental illness. Drake learns to hide it
from his hosts and plots to fulfill his dream.

He tells his patron that he will take a ship on a sight-seeing tour of the solar system. Part-way through
the tour, he sets a course for Pluto where the cryogenic crypts are kept. He steals the cryowomb
where Ana lays waiting and programs a large looping course. By using relativistic effects, he makes
another sojourn into the future.

Skipping forward through time, he encounters the human race as it evolves. He is told that there is only
one chance to be reunited with Ana, to be with her when the Omega Point occurs. The Omega Point is the
reverse of the Big Bang, when the entire mass of the universe contracts back into a singularity. And at
that moment, one can create a new reality. His goal now is to survive the 50 billion years until the Big
Crunch. Before he can proceed, he needs to save the galaxy from an invading force -- a task he alone can do
because of his primitive, aggressive nature.

Charles Sheffield shows us one possible future, both for humankind and for the universe. With his firm
grounding in math and physics he lays out what happens in a closed universe -- one that will collapse in on itself.

The story is highly imaginative and the plot has many inventive twists. For instance, if a collective
consciousness is possible, then what happens if that collective consciousness is composed of multitudes
of the same person, sent out in different directions, then reassembled?

I enjoyed the story very much, but I was bothered by three details, one psychological and two
technological. Drake Merlin had to be obsessed, and truly bordering on mentally ill, in his desire to meet up
with his Ana in the future. Yet we overlook this obsession, perhaps because we associate it with a
quest, and because it is for love. One of the technological details is that, despite the passage of
millions or billions of years, Drake is still capable of remembering all that has happened to himself during that
time. Yet there isn't any description of how to store, much less access that much
information. Finally, over the time frame that is described, billions of years, I would have expected
a larger change in humankind. In fairness though, humans would learn how to exert control and might
decide to not change as radically as we "naturally" would.

In an appendix, the author provides a scientific discussion about the collapse of the universe, in addition to
another possible future where the universe continues to expand without limit. With today's knowledge,
the scientific community has not been able to determine which scenario will happen. This scientific
essay is the most readable since those of Isaac Asimov. It provides the reader with a greater understanding
of the science without requiring an advanced degree.
